Given numbers are 868,209,299,221

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 868,209,299,221 is 922117196.

Find LCM of 868,209,299,221 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

13 x 868 x 209 x 23 x 17 = 922117196

Therefore, the lowest common multiple of 868,209,299,221 is 922117196.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

868 x 209 x 299 x 221 = 11987523548

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868

209 : 1, 11, 19, 209

299 : 1, 13, 23, 299

221 : 1, 13, 17, 221

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 868,209,299,221, is 1.

Now, the common factors can be found like this.

868:2x 2x 7x 31

209:11x 19

299:13x 23

221:13x 17

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

13 = 13

Therefore, the value for common factors is 13.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 11987523548/(1x13)

LCM = 11987523548/13

LCM = 922117196

Thus, we can understand that the LCM of 868,209,299,221 is 922117196.
